Abstract: 將AE-42便攜式黑炭(BC)儀和GPS接收機同時搭載到汽車平臺上組成移動觀測系統,測量徐州市區主干道路的BC氣溶膠濃度。觀測及分析揭示:徐州市外環區域的BC氣溶膠濃度較高,主要來源于工業排放和機動車尾氣,尤其是柴油機動車尾氣的排放;市中心區的BC氣溶膠質量濃度較低,與人的出行活動密切相關;主要交通干道的BC氣溶膠濃度取決于交通密度和街道特點,在不同時段內會呈現明顯的高低分布差異。實驗表明,AE-42便攜式BC儀和GPS接收機組成的移動觀測平臺便捷有效,具有靈活機動性和推廣應用價值。
In this paper,a black carbon(BC)concentration measurement experiment along the main roads of Xuzhou downtown is done by using a mobile measuring system,which is consisted of an AE-42portable BC Aethalometer and a GPS receiver carried by a moving car.Analysis to the measurements revealed that:1)the BC aerosol concentration along the main roads of Xuzhou tends to be higher,and comes mainly from industrial emission and vehicle exhaust,especially the exhaust from diesel vehicle;2)the BC aerosol concentration at downtown center is lower,and is closely related to citizens′activities;3)the BC aerosol concentration along the main roads of Xuzhou is dependent on traffic density and road limitation,and it gets variable with time difference.The experiment and results illustrate that the mobile measuring platform,consisted of an AE-42portable BC Aethalometer and a GPS receiver,has characteristics of convenience,effectiveness and flexibility,and has potential application in other cities.
